OK. That is reasonable.  CPU load can go up to  N * 100% with N = number
of CPU-cores.

200% CPU usage (as displayed by top) means on average two of your CPU
cores are busy. On a quad-core system that's nothing to worry about. It
shows that Mixbus' parallel-processing works as designed.

Total load depends on plugins and track-count (in Mixbus every track
does DSP).
